Are these real shares?
They are Robinhood's stock tokens on Robinhood Chain: each tracks one share of the company, issued by Robinhood. A grant holds the tokens themselves, and the recipient receives the tokens themselves.
What does the recipient need?
A wallet on Robinhood Chain and a little ETH for the claim's gas. They don't need to do anything until they want their shares.
What happens when a stock splits?
Robinhood's tokens apply splits and similar corporate actions through a share multiplier, so a grant of 10 tokens always shows the right number of shares — Rill reads the multiplier from each token.
What if the price passes my target and falls back?
A price-unlocked grant unlocks while Robinhood's price is at or above the target. The recipient should claim while it is: if the price falls back first, it locks again until the price returns or the end date arrives. What they have claimed is theirs for good.
Can I cancel a grant?
If you left it cancellable, yes: everything not yet vested returns to your wallet in the same transaction, and the recipient keeps what has vested. You can also make a grant permanent at any time — that can't be undone.
Is there a Rill fee?
No. You pay Robinhood Chain gas, and Uniswap's pool fee if the app buys the shares for you. Sablier can charge a small ETH fee to claim; on this chain it is 0 ETH today.
